The period on the periodic table(1-7) tells you the number of ________ in an atom.
A. energy levels
B. electrons on the last energy level
Answer:
Electrons on the last energy level.
The period on the periodic table (1 to 7) tells the number of energy levels in an atom. Therefore, option A is correct.
What are periods in the periodic table?The horizontal rows in the modern periodic table are known as periods. All elements placed in a particular period have an equal number of electron shells. Each next element exceeds one proton in a period and so exhibits less metallic character than its precursor.
The atomic number of the elements increases from left to right in a period that gives information about the number of electrons and protons increases in an atom. As in a period, elements have filled an equal number of electron shells, but an increased electron in the same shell causes an increase in the nuclear charge. Therefore, the atomic radius of an element of the elements reduces in a period.
Therefore, the elements in the same period (1 to 7) have the same number of electron shells or energy levels.

The diagram shows the moon and Earth in space. Which is the best label for the dotted-line arrow?
O force of Earth's gravity
O moon's attraction to the Sun
moon's motion without gravity
O orbit of the moon around Earth
arth
Answer:
The answer is c) moon’s motion without gravity
Explanation:
I just took the quiz and I got 100 percent on Edgenuty :)
The dotted-line arrow is representing the path the moon would take if there was no force of gravity on the earth. Therefore, option (C) is correct.
What is gravity?Gravity can be explained as a force that attracts an object toward the center of the earth or any physical system that has mass. Each body with mass exerts a force or gravity on every other body with mass. Gravity is the force that keeps the moon around the earth and the planets in orbit around the sun.
In the universe, each particle with mass attracts another particle with a definite force, and that force acting is a product of the masses of those bodies.
Mathematically gravity acting between masses can be written as:
[tex]F =G\frac{q_1q_2}{r^2}[/tex]
Where F is the force, m and M are masses, G is the universal gravitational constant and r is the separation between them.
If the moon follows the dotted arrow which moves straight ahead it can be only possible if the moon's motion is without gravity.

Non-examples of stars: Earth, Moon, Planets.
Why Sun is a star?The Sun, a 4.5 billion-year-old yellow dwarf star and the center of our solar system, is a hot, burning ball of hydrogen and helium. It is the only star in our solar system and is located approximately 93 million miles (150 million kilometers) from Earth. On our home planet, life as we know it would not be possible without the energy of the Sun.Despite being the hub of our solar system and crucial to our existence, the Sun is simply an average-sized star. There have been found stars up to 100 times bigger. Additionally, many solar systems contain multiple stars.

sorry honey, I don't know 4
can anyone help me with this question. is there anybody who is an expert in science??
Answer:
Explanation:
GIVEN ; FORCE = 2000 NEWTON
DISPLACEMENT = 10 M
TIME = 50 SECONDS
AS WE KNOW , POWER = WORK / TIME
= WORK = FORCE × DISPLACEMENT = 2000 × 10
= 20000 JOULES
THEN, POWER = 20000/ 50
SO, POWER = 400 WATT ( JOULES / SECOND )
Which properties describe elements that are nonmetal gases?
Answer:
Explanation:
Nonmetals share many similar properties including:
They are either gas (hydrogen, oxygen, nitrogen) or solid (carbon, sulfur) under standard conditions.
They are not good conductors of electricity or heat.
They are very brittle in their solid form.
They are not malleable or ductile.
Select the correct answer. Consider an atom that has an electron in an excited state. The electron falls to a lower energy level. What effect does that have on the electron? A. The electron releases energy in the form of light. B. The electron absorbs energy in the form of light. C. The electron retains its energy without any change. D. The electron transfers its energy to other electrons.
Answer:
A
Explanation:
The more energy u give the more the electron is able to get far away from the nucleas. So the opposite happens when u take away some energy, it will falll on lower energy state and will radiate the energy difference in form of a photon/light.

3. A hawk gets some help while flying by using convection
currents (air currents created by rising warm air). How is the Sun
involved in creating convectior currents?
Answer:Explanation:
Convection drives the circulation of air in the earth's atmosphere. The sun heats the air near the earth's equator, which becomes less dense and rises upward. As it rises, it cools and becomes less dense than the air around it, spreading out and descending toward the equator again.

what is neons destiny and mohs hardness
The number of electrons in each of Neon's shells is 2, 8 and its electronic configuration is 1s2 2s2 2p6.
...
Neon Properties.
Melting Point: -248.59°C, -415.462°F, 24.56 K
Neon's destiny is to produce vibrant and attractive colors in neon signs, while Mohs hardness is a scale used to measure the hardness of minerals, and it does not apply to the element neon.
Neon's destiny refers to the role or purpose of the element neon in the natural world. Neon is a noble gas that is commonly used in neon signs due to its vibrant red-orange color when electricity is passed through it. Its destiny, in this context, is to create visually appealing and eye-catching signs.
On the other hand, Mohs hardness is a scale that measures the hardness of minerals. It was developed by Friedrich Mohs in 1812. The scale ranges from 1 to 10, with 1 being the softest and 10 being the hardest mineral.
Now, let's discuss the Mohs hardness of neon. Neon is an element, not a mineral, so it does not have a specific Mohs hardness value. The Mohs hardness scale is specifically designed for minerals, not elements. Therefore, we cannot assign a Mohs hardness value to neon.

ethane is a substance that is used when making plastic. a molecule of ethane is made of two carbon atoms and six hydrogen atoms. the carbon atoms are joined by the chemical bond. each of the hydrogen atoms is joined to one of the carbon atoms by a chemical bond. which is an accurate model of ethane?
Help ASAP!!!
Answer:
C
Explanation:
Option C is an accurate model of ethane.
Ethane is an alkane that has two carbon atoms bonded together and each atom has three hydrogen atoms that are attached to them. Ethane has single bonds and that makes it an alkane.
This model of ethane has six carbon-hydrogen bonds shown with solid lines that are protruding out. Rotation that takes place about the carbon-carbon bond actually results in the different molecular conformations of ethane.

Which of the following statements is true? Atoms of isotopes of an element have different numbers of electrons. Atoms of isotopes of an element have different numbers of neutrons. Atoms of the same element all have the same mass. Atoms of isotopes of an element have different numbers of protons.
Answer:
atoms of isotopes of an element have different numbers of neutrons.
Explanation:
isotopes have the same number of protons, but different numbers of neutrons.
Two or more than two atoms with different physical or chemical properties can not combine together to form an element. Atoms of isotopes of an element have different numbers of neutrons.
What is element?Element generally consist of atoms or we can atoms combine to form element. Atoms of an element is always same, means all the properties of all atoms of one type of element is same.
One element can have isotopes of its own. Isotopes are the atoms of element with same atomic number but different mass number. Example Hydrogen has three isotopres like hydrogen, deuterium and tritium with mass number 1, 2 and 3 respectively. Atoms of isotopes of an element have different numbers of neutrons.
